SAW-FILE GUIDE.

SPECIFICATION forming part of Letters Patent No. 537,827, dated April23, 1 895.

Application filed July fl, 1894. Serial No. 516 ,389- (No model.)

T0 at whom it may concern:

Be it known that I, AUGUST KAEMPFER, a citizen of the United States,residing at Sheboygan, in the county of Sheboygan and State anism fromthe under side, with the slotted guide plates broken away. Fig. 3 is adetail view showing the slotted guide plates set with the guide bar atright angles to the parallel bars (3 O. v

Like parts are referred to throughout by means of the same referenceletters.

The saw A is supported in the vice B with the teeth upward. A bar orbars 0, preferably two parallel bars, are provided at each end with theattaching clamps D adapted to engage against the sides of the saw and tosupport the bars 0 above, and approximately parallel to the line of thesaw teeth as shown in Fig. 1. A traveler E is adapted to be supportedand guided by and between the bars 0, and is provided on its under sidewith the segment F, having the adjusting notches G. Pivotally supportedunderneath the plate E is the adjusting finger H provided withdownwardly projecting flanges I I, and the upwardly projecting lug Jwhich is adapted to fit into the notches G of the segment. The pivotbolt K passes up through the plate E and is provided with the thumb nutL for the purpose of tightening the finger H and looking it in placewith the lug J in one of the notches G. Slotted guide plates M M,preferably formed in a single piece as shown, are hinged to the flangesI I and may be located in any position by means of the thumb nut N, onthe hinge bolt 0,- thus enabling the operator to adjust the guide plateswith the slots P P at any desired inclination from the vertical.

The guide bar R is removably attached to the file S, by means of thebracket F, provided with a set screw U, and is adapted to operatethrough the slots P P and guide the file S between the saw teeth.

By means of the adjusting finger H, the guide plates M M may be so setas to guide the file at any angle across the saw, necessary to give theteeth the desired bevel, and by means of the hinge bolt 0 and thumb nutN,

the file may be held at-any desirable inclination. The travelerE permitsthe guide mechanism to slide along the bars 0 O and bring the file inposition to operate upon the saw teeth in succession.

In order that the Tile may be brought to bear upon the end teeth of thesaw, I have provided an extension plate V attached to the end of the sawby the clamp W and set screw X. The outer clamp D can then be attachedto the plate V, as shown in Fig. 1.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. A saw file guide, consisting of the combination of the bars 0, clampsD, traveler E, adjusting finger H, means for locking said finger H atany desired adjustment, slotted guide plates M M hinged to saidadjusting finger, and means for locking said hinge with the slots at anydesired inclination, together with a guide bar removably attached to afile and adapted to slide in said slots and guide said file between thesaw teeth, substantially as described.

2. In a saw file guide, substantially as de-'
